We report on the recent NIR flare of the high redshift QSO (z=1.05) BZQJ1127-1857 also known as CGRaBSJ1127-1857 cross correlated with the Gamma-ray source 3FGLJ1127.0-1857. On March 18th,2017 MJD(2457830.8924) we found the source with NIR fluxes corresponding to J = 14.628+/- 0.03, H = 13.949 +/- 0.02 and Ks = 13.077 +/- 0.07. While, on MJD 2457817.810 the flux in the H band corresponded to H = 14.682 +/- 0.03. Hence, the source has doubled its flux in this short lapse. This source has shown multiwavelength flaring activity in the past (see ATEL #3207,#3212, #4820). Our observations are carried out with the 2.1m telescope of the Guillermo Haro Observatory operated by the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We encourage further multi wavelength coverage.
